Comparison of Total Degree of Transversality of Palmar Creases between Students & Labourers Using Novel Method of Digital Photography
ABSTRACT Objectives: To estimate the Total degree of transversality (T-DoT) of major palmar creases between students and manual labourers using digital photography. Materials and Methods:Fifty healthy adult volunteers, postgraduate students and constructional labourers were studied. T-DoT was measured by drawing coordinators using digital photographic methods and ADOBE Photoshop. Appropriate statistical tests were applied to determine the tests of significance between the two groups for T-DoT. Results: The mean value T –DoT of students right hand was 1.21 ±0.19, left hand was 1.14 ±0.2. The mean value of T-DoT of labourer’s right hand was 1.33 ±0.34, left hand was 1.30 ±0.31. No significant difference was found between the right and left hands of the groups (Students (p=0.09), labourers’ (p=0.724)). On comparing the T-DoT between the right and left hands of the two groups, statistically significant difference (p=0.046) was found between the left hands of the two groups. Conclusion: There was a significant difference in T-DOT in left hand between the two groups. This can be attributed to the equal usage of both hands by labourers which were not the case with the students. So before correlating palmar creases for various diseases with the T-DOT, occupation and hand grip needs to be considered by the clinicians. Keywords: T-DoT, Palmar creases, Hand Grip
